About our fire rated sealant in Belmont
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. Common call-outs are for sealant items on a fire risk assessment action list and linear gaps at the head of walls, across plasterboard & masonry, pipe & cable gaps and linear gaps. Whether you are looking for a mastic man, a sealant applicator or a sealant contractor in Belmont, that’s what we do.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Belmont needs to stay open, work can be planned outside normal hours.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Common problems we fix in Belmont
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Most people get in touch when they notice one of these:
- Seals cut through by electricians, plumbers or data installers
- Old fire sealant that has split or come away
- Open gaps behind door architraves
- Open joints along the top of partitions
If you look after a building such as Avenue Primary Academy, service openings in fire-resisting walls need checking after any refurbishment.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Questions from Belmont
I let a flat near Belmont station. Can you help?
Yes, rental work is part of what we do. You can phone 07833 053749 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can parking be tricky for a visit in Belmont?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do you come to Belmont?
Yes. We work in Belmont and the rest of Greater London. To book, phone 07833 053749 or email us.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
What the job involves on each surface
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.
Commercial buildings in Belmont
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
For buildings such as Church of St John, service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Belmont station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Get damaged fire seals looked at promptly
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
